Best for
  • Teams evaluating RAG pipelines
  • Developers adding eval to CI/CD
  • RAG researchers and practitioners
  • Teams operating at large scale
  • Billion-vector search workloads
  • Enterprise RAG and search
Pros
  • Focused, research-backed RAG metrics
  • Free and open source
  • Reduces need for manual labeling via LLM scoring
  • Synthetic test-set generation
  • Broadened to LLM and agent evaluation
  • Open source under Apache 2.0, free to self-host
  • Proven at billion-vector scale
  • Distributed, cloud-native architecture
  • Multiple index types and GPU acceleration
  • Hybrid search and rich filtering
Cons
  • LLM-as-a-judge scores need validation
  • Mainly a library; you build dashboards/infra
  • Judge model choice affects reliability and cost
  • Python-only
  • Less turnkey than managed eval platforms
  • Operationally heavy to self-host at scale
  • Multi-component architecture adds complexity
  • Overkill for small or simple projects
  • Steeper learning curve than embedded databases
  • Zilliz Cloud compute-unit pricing needs modeling
